Reactor antineutrino anomaly revisited circa 2021

Abstract

In our recent work [1], we study the status of the reactor antineutrino anomaly in light of new reactor flux conversion and summation models. We present a new improved calculation of the IBD yields of the standard Huber-Mueller (HM) model and those of the new models. We show that the reactor rates and the fuel evolution data are consistent with the predictions of the Kurchatov Institute (KI) conversion model and with those of the Estienne-Fallot (EF) summation model, leading to a plausible robust demise of the reactor antineutrino anomaly. We also show that the results of several goodness of fit tests favor the KI and EF models over other models under consideration.
